CouchRest: CouchDB, close to the metal

Build Status

CouchRest wraps CouchDB's HTTP API using persistent connections with the HTTPClient gem managing servers, databases, and JSON document serialization using CouchDB's API endpoints so you don't have to.

CouchRest is designed to provide a simple base for application and framework-specific object oriented APIs. CouchRest is Object-Mapper agnostic, the JSON objects provided by CouchDB are parsed and returned as Document objects providing a simple Hash-like interface.

For more complete modelling support based on ActiveModel, please checkout CouchRest's sister project: CouchRest Model.

CouchDB Version

Tested on latest stable release (1.6.X), but should work on older versions above 1.0. Also known to work on Cloudant.


$ sudo gem install couchrest

Basic Usage

Getting started with CouchRest is easy. You can send requests directly to a URL using a RestClient-like interface:

CouchRest.put("http://localhost:5984/testdb/doc", 'name' => 'test', 'date' => Date.current)

Or use the lean server and database orientated API to take advantage of persistent and reusable connections:

server =           # assumes localhost by default!
db = server.database!('testdb')  # create db if it doesn't already exist

# Save a document, with ID
db.save_doc('_id' => 'doc', 'name' => 'test', 'date' => Date.current)

# Fetch doc
doc = db.get('doc')
doc.inspect # #<CouchRest::Document _id: "doc", _rev: "1-defa304b36f9b3ef3ed606cc45d02fe2", name: "test", date: "2015-07-13">

# Delete

Running the Specs

The most complete documentation is the spec/ directory. To validate your CouchRest install, from the project root directory use bundler to install the dependencies and then run the tests:

$ bundle install
$ bundle exec rake

To date, the couchrest specs have been shown to run on:

  • MRI Ruby 1.9.3 and later
  • JRuby 1.7.19
  • Rubinius 2.5.7

See the Travis Build status for more details.
